Description: 一1000 MW水电站(机组M1)通过一条500 kV, 700 km的输电线路与负载中心连接。负载中心模型是5000 MW的阻抗负载,由遥远的1000 MW电站和当地的5000 MW (机组 M2)电站供电。系统已经初始化,因此线路传送950 MW,接近它的潮流阻抗负载(SIL = 977 MW)。这两台机相当于一台水轮机和管理(HTG),励磁系统和电力系统稳定器(PSS)。这三个模块位于“涡轮和调速”子系统中。通过此例,在500 kV系统中制造故障,观察PSS对系统稳定性的影响。-a 1,000 MW hydropower station (crew M1) through a 500 kV, 700 km of transmission line and load center. Load center model is 5,000 MW of load impedance. from the distant 1000 MW power station and the local 5,000 MW (Unit M2) power supply. Is initialized, it transmits 950 MW. closer to its trend of load impedance (SIL = 977 MW). This machine is equivalent to a two hydraulic turbines and Management (HTG), excitation system and the power system stabilizer (PSS). This module is located at 3 "and turbine speed" subsystem. Through this cases, the 500 kV system manufacturing fault, PSS observation of the system stability. Platform: |

Description: ST7529液晶驱动 The ST7529 is a driver & controller LSI for 32 gray scale graphic dot-matrix liquid crystal display systems. It generates 255
Segment and 160 Common driver circuits. This chip is connected directly to a microprocessor, accepts Serial Peripheral
Interface (SPI), 8-bit/16-bit parallel or IIC display data and stores in an on-chip display data RAM. It performs display data
RAM read/write operation with no external operating clock to minimize power consumption. In addition, because it contains
power supply circuits necessary to drive liquid crystal, it is possible to make a display system with the fewest components.-ST7529 LCD driver The ST7529 is a driver Platform: |

Description: full wave rectifierDuring the period from 伪 to 蟺, the input voltage vs input current is are positive and the power flows from supply to the load. The converter is said to be operated at rectification mode .During the period from 蟺 to 蟺+伪 , the input voltage vs is negative and the input current is is positive and reverse power flows from load to the supply. The converter is said to be operated in inversion mode. Depending on the value of 伪, average output voltage can be either positive or negative and hence provides 2 quadrant operation.
